Freddie Mercury, the frontman of Queen, is often cited as the greatest lead singer in the history of rock. A scientific study in 2016 analyzed his voice and found that his vocal cords moved faster than the average person's, and he possessed a rare 'subharmonic' vibrato. While he was naturally a baritone, he often sang in the tenor range with incredible power. His masterpiece, 'Bohemian Rhapsody' (1975), showcased his ability to blend opera with hard rock, a feat previously thought impossible for a pop single. Mercury's stage presence was equally legendary, culminating in Queen's 1985 Live Aid performance, which is frequently voted the greatest live show in history. Mercury was also a talented songwriter, penning hits like 'Somebody to Love' and 'We Are the Champions' before his death in 1991.
